Smatra se da je meteor velikom brzinom u\u0161ao u atmosferu te eksplodirao na visini od pet do deset tisu\u0107a metara iznad tla. Udar je sru\u0161io oko 80 milijuna stabala na podru\u010dju od oko 2150 kvadratnih kilometara, iako nije udario o tlo. Eksplozija je bila oko tisu\u0107u puta ja\u010da od<br \/>\neksplozije nuklearne bombe u Hiro\u0161imi.<\/p>\n<p>Zanimljiva je bila i <em>radionica s udarnim <\/em><em>kraterima.<\/em> Na podu se nalazila kutija koja je simulirala povr\u0161inu Marsa \u2013 sloj pijeska, sloj bra\u0161na, sloj crvene paprike. U\u010denici su s iste visine bacali pikule i kuglice razli\u010ditih veli\u010dina i te\u017eina, mjerili \u0161irinu kratera, zapisivali dobivene<br \/>\npodatke te pratili mije\u0161anje slojeva pri udaru. Zatim su promatrali \u0161to napravi<br \/>\ntijelo koje je ispaljeno ve\u0107om brzinom (pra\u0107kom te dje\u010djim pi\u0161toljem s<br \/>\nplasti\u010dnim kuglicama). Saznali su da je energija jednaka umno\u0161ku mase tijela i<br \/>\nkvadrata njegove brzine podijeljene s dva.
